Titre : Naturalization of Prunus laurocerasus in a forest in Germany Type de document : Imprimé Auteurs : Stefan Abrahamczyk ; Johanna Otto ; Tim Böhnert ; Maximilian Weigend Année de publication : 2024 Article en page(s) : 2379-2386 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Prunus laurocerasus L., 1753 Résumé : The cherry laurel (Prunus laurocerasus) is a very popular garden plant and has been widely reported as a garden escape in Central Europe. However, it is still considered an unestablished neophyte in Germany. Few critical data are available on local population sizes, life history or reproductive biology outside its natural range. We carried out a study with 24 transects of 500 m × 6 m in the Kottenforst near Bonn, western Germany to fill these knowledge gaps. Along these transects we recorded the plant number and plant sizes and analysed their age structure. We found Prunus laurocerasus along 19 of 24 transects with up to 63 individual per transect. The largest plants covered areas of up to 50 m2 and were up to 30 years old. However, most of the plants were less than 20 years old and established since 2000. Since we observed high fruit set and old plants surrounded by many seedlings we conclude that Prunus laurocerasus has to be considered as an established neophyte in our study area and has invasive potential.

Titre : The reproductive biology of the neophyte Prunus laurocerasus in Central Europe Type de document : Imprimé Auteurs : Stefan Abrahamczyk ; Johanna Otto ; Maximilian Weigend Année de publication : 2025 Article en page(s) : 167-174 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Prunus laurocerasus L., 1753 Résumé : Cherry laurel (Prunus laurocerasus) is a very popular garden plant and has been widely reported as a garden escape, for example, in Central Europe. We recorded flower visitors and consumers of fruits and conducted pollination experiments to improve our understanding of the degree of ecological integration of P. laurocerasus in the newly colonized range in Central Europe. We observed a range of different flower visitors, especially bees and syrphid flies. Bee visitation rates decreased with increasing canopy cover, whereas fly visitation rates were independent of canopy cover. Prunus laurocerasus is reported as outcrossing in its native range, but we could demonstrate that the plant is facultatively selfing in our study area. Open pollination led to abundant fruit set, and fruit consumption by common blackbirds was observed. Overall, our study documents that the reproductive ecology of P. laurocerasus is well adapted to the conditions (e.g., pollinators, seed dispersers) of the newly colonized range in central Europe and underlines the invasive potential of the species.
